Calderan Rapids

The Calderan Rapids refer to a phenomenon caused by the Calderan Fissure, the Calderan Sea and the Blue Sea.

The Calderan Rapids span over 50 km from the northern edge of Groftlan to the edge of the Eyrsan crest, creating a full divide between the Calderan and Blue Seas. At its widest point the rapids are 300m wide. The drop in the various "sea levels" of the Calderan and Blue seas is roughly measured at 7 meters.

The constant eruptions of the geyers making up the Calderan Fissure create outward currents to the west and east, feeding the Calderan and Blue seas, respectively.
